Twain

Privacy Policy

Last updated: May 2026

Who we are

Twain is operated by Twain Club LLC, a Connecticut limited liability company (“Twain,” “we,” or “us”). This Privacy Policy describes how we handle personal information collected through the Twain platform at app.twain.club and related services.

Who's the data controller

Twain operates a multi-tenant software platform. Each private club using Twain (a “Club”) is the data controller for its members’ personal information. Twain Club LLC is a data processor acting on each Club’s instructions. For inquiries about your member record, contact your Club directly. For inquiries about the platform itself, contact us at privacy@twain.club.

What we collect

  • Account info: name, email, phone number, membership category, club affiliation.
  • Member intelligence: dietary restrictions, allergies, dining preferences, VIP and veteran flags, special notes — supplied by the member or the Club.
  • Activity data: dining reservations, event RSVPs, charges and statements, communication preferences and history, audit log entries.
  • Technical data: IP address, browser, session cookies for authentication, opt-out tokens for one-click unsubscribe.

How we use it

  • To deliver the Club’s services to its members.
  • To send communications you or your Club have requested: transactional SMS (account-related notifications you opted into), transactional email, and opt-in marketing email. SMS is transactional only — promotional content is delivered via email.
  • To honor opt-out, STOP, and unsubscribe requests across SMS and email.
  • To diagnose and improve the platform (in aggregate where possible).
  • To comply with legal obligations and enforce our Terms.

Third-party processors

We share necessary information with the following sub-processors, each contractually bound to use the data solely for service delivery:

  • Supabase (database hosting · United States)
  • Vercel (application hosting · United States)
  • Resend (transactional and marketing email)
  • Twilio (SMS delivery and inbound webhooks)
  • Stripe and Square (payment processing — payment cards never traverse Twain’s servers)
  • DocuSign (electronic signatures for reciprocity letters and inter-club agreements)
  • QuickBooks (accounting integration where the Club has connected one)
  • HubSpot (membership recruitment funnel where the Club has connected one)

Retention

Member records are retained as long as the Club’s membership relationship is active, plus a reasonable period thereafter to satisfy audit and dispute resolution. Deletion requests are honored on the Club’s instruction, subject to legal retention requirements (e.g. accounting records).

Your rights

Depending on your jurisdiction, you may have the right to access, correct, delete, or port your personal information, and to object to or restrict certain processing. To exercise these rights, contact your Club directly or write to privacy@twain.club.

Communications opt-out

Email: every marketing email contains an unsubscribe link honoring RFC 8058 one-click unsubscribe. Critical billing and governance messages cannot be opted out of while a membership is active.

SMS: reply STOP to opt out globally. See our SMS Communications policy for details.

Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be communicated to Clubs and reflected by an updated “Last updated” date.
